Description

The present application relates to a woven fabric coloring technique, and specifically relates to a woven fabric coloring method and a colored woven fabric.

In the conventional color system, when distinguishing according to the coloring principle, there are mainly two kinds of coloring methods, that is, the color of the dye and the color of the structure. The color of the dye depends mainly on the chemical bonds in the substance molecule, and while the electrons in some chemical bonds tend to absorb visible light of a specific wavelength, the remaining other wavelengths are reflected and differ. It is designed to be presented as a color. A substance capable of achieving such an effect is a pigment, and such a color is called a pigment color. The color of the dye can be understood as one unique property of the material.

The color of the structure, also called the physical color, is a special structure on the surface of the object that causes the light wave to be refracted, diffusely reflected, diffracted, or interfered with, changing the composition of the light. While increasing the light intensity of a part of a particular wavelength in the light spectrum, part of it becomes weaker and eventually the object exhibits a different color. Metallic luster and light on the surface of the beetle's body wall are typical structural colors.

Traditional coloring of woven fabrics mainly depends on the color development by the color of the dye, specifically, dyeing with a dye for the chemical industry, and is mainly generated by giving the dye to the base fabric. Currently, the dyeing and finishing industry-wide dyeing and finishing process generally involves steps such as pretreatment, dyeing, pattern dyeing and finishing. However, traditional dyeing methods
1. The dyeing and finishing industry belongs to the industry that is currently strictly regulated in Japan, and the amount of water consumed for dyeing cloth per 100 meters is 2 to 4 tons, and the amount of wastewater in the total water consumption is It is 60 to 80%. At the same time, the drawbacks of producing volatile pollutants during the preparation and production of dyes,
2. Dyeing with conventional chemical industrial dyes mainly relies on adsorption and fixation between the dyeing group and the textile fibers, but the process is very dependent on the fiber structure and therefore different fabrics. In the case of fabrics, they need to be used in combination with different dyes and auxiliaries, for example nylon fabrics mainly use acidic dyes and acrylic fabrics mainly use cationic dyes or disperse dyes. The acetate fiber woven fabric mainly uses disperse dyes, but sometimes dyes with insoluble azo dyes, so the universal adaptability of pigments is inferior.
3. Traditional dyeing is mainly done with liquid dyeing agents, and there is a big difference in the degree of shrinkage and curling of woven fabrics due to different knitting methods, so the equipment used for dyeing woven fabrics with different knitting methods is also different. The existence of the drawbacks is clear.

Given the above-mentioned defects in traditional chemical dyeing, how to effectively construct structural colors with textile materials has already been the focus and research of the textile dyeing and finishing industry. It is an issue to do. For example, using magnetron sputtering technology, radio frequency sputtering is performed on a woven fabric base (base cloth) to form a periodic film alternating _{with SiO 2} and TiO _{2 on the surface of the base cloth.} When illuminated by light, the colored fabrics become bright and vibrant. The coloring technique mainly utilizes the interference of light generated by alternately and periodically arranging a _{SiO 2} film having a low refractive index and a TiO _{2 film having a high refractive index to make a colored fabric bright and vivid.} It is made to exhibit a unique color.

Since the above coloring technology eliminates the discharge of waste water, waste of water resources and pollution to the environment are avoided, and at the same time, the adaptability to the base cloth is widened, and the fibers of the base cloth are natural such as mulberry pure silk. It may be a protein fiber or a chemical fiber such as polyester or nylon. However, since this coloring technology realizes color development by using the interference effect of periodic titanium dioxide and silica on light of only two types of film layers, the types of colors to be finally presented are greatly limited. With this coloring technique, which is extremely sensitive to film thickness, it is very difficult to achieve the ideal yield in actual production, so the spread of industrialization by the coloring technique is greatly limited. In addition, the discoloration resistance of the woven fabric by the coloring technique cannot be guaranteed.

Currently, a method of slightly increasing the color richness by adopting vacuum vapor deposition technology and depositing other metal units or alloys on the fiber surface has been reported in a small amount of literature, but the method is carbon fiber. It is limited to the coloring of a few special fibers such as polyimide, and does not apply to fibers such as traditional shavings and pure silk. This is reflected in the discoloration resistance, which does not meet national standards, mainly because the colored fabrics are not uniformly colored and there is no film deposition in some areas.

Thus, not only does the fabric produce a rich color, but the resulting colored fabric has very good discoloration resistance, while at the same time satisfying the production requirements of the industry, universal for textile fibers. Developing a coloring method that is highly adaptable is currently an urgent issue to be resolved.

In response to the above defects, the embodiments of the present disclosure provide a method for coloring a woven fabric, which not only produces a rich color but also reduces the sensitivity of the color to the thickness of the film layer, and is therefore industrial. Improve operability. At the same time, the universal adaptability of the coloring method to the fibers is improved, and it is possible to make the colored woven fabric have excellent discoloration resistance.

In the examples of the present disclosure, a colored woven fabric prepared by the above-mentioned coloring method is also provided, and the colored woven fabric is not only provided with rich color and good discoloration resistance, but also prepared by an industrialized method. You can also get it.

In order to achieve the above object, in the embodiment of the present disclosure, a method of coloring a woven fabric is provided, and the method is described.
Steps to perform a radiative drying process on the base fabric,
By vacuum deposition, an adhesive layer and at least one color-developing layer are gradually formed on the surface of the base fabric after being dried by radiation.
The structure of the adhesive layer is made to contain at least one of Ti, Cr, Si and Ni elements so that the thickness is 1 to 2000 nm.
The composition of the color-developing layer is made to contain at least one of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au and Mg elements so that the total thickness of the color-developing layer is 4 to 2000 nm. Including steps to make.

According to the coloring method provided in the examples of the present disclosure, a vacuum deposition technique is applied to form a color-developing film layer including an adhesive layer and a color-developing layer on the surface of the base fabric, and nano with different materials and different thicknesses against light. Utilizing the integrated action of absorption, reflection and refraction of the film layer, the obtained colored fabric is made to exhibit different colors.

In addition, if the materials used for the adhesive layer and the coloring layer, the thickness of each film layer, and the arrangement method of the film layers are changed, the color of the colored woven fabric will change accordingly. Gives the possibility of richer colors and more colors. Therefore, by appropriately adjusting and arranging at least one of the above elements according to the required color of the woven fabric, the dependence of the color of the woven fabric on the thickness of the film layer can be significantly reduced. This is advantageous for the realization of the textile coloring industry.

At the same time, by the coloring method, a colored woven fabric including discoloration resistance to water, discoloration resistance to sweating, discoloration resistance to friction, discoloration resistance to soaping, discoloration resistance to dry cleaning, discoloration resistance to light, etc. The discoloration resistance has reached level 4 or level 4 to level 5, and meets the requirements of the GB / T2660-2017 "shirt" standard for first-class products and even superior products.

According to the research of the inventor, the coloring method for the base cloth fiber has good adaptability, and the base cloth fiber for coloring may be a carbon fiber which is difficult to be dyed with a traditional chemical industry dye, and is synthesized such as polyimide. It has been discovered that it may be a fiber, a synthetic fiber such as polyester, nylon, spandex, which is commonly found today, or a natural fiber such as traditional cotton, linen, silk.

In addition, the coloring method is highly adaptable to the knitting method of the base fabric, and the base fabric obtained by knitting or tatting can be colored by using the above coloring method and is resistant to discoloration. Is good.

Based on the above phenomenon, the inventor relies mainly on high-energy bonding formed by the color-developing film layer and the base cloth with the cooperation of high-energy ions, and this type of bonding is the main cause of the occurrence. Because it is affected by the strength of the surface energy of the base fabric and the ease of atom transfer in the adhesive layer, and is not sensitive to the fiber type and knitting method of the base fabric, the coloring method uses different base fabrics and knitting methods. It was analyzed that the shift is also applied to different base fabrics.

The coloring equipment used in combination with the coloring methods provided in the examples of the present disclosure is also very universally adaptable, eliminating the need to design corresponding dyeing equipment for base fabrics with different knitting methods. Therefore, it is not difficult to understand that it further improves industrial operability.

According to the technical solution according to the embodiment of the present disclosure, the adhesive layer is for improving the adhesive force between the surface of the base fabric and the color-developing layer. Specifically, for the adhesive layer, elements such as Ti, Cr, Si, and Ni, which generally have good diffusion performance, can be selected. In the specific implementation process of the examples of the present disclosure, the adhesive layer is
1. The adhesive layer is a single layer of Ti, Cr, Si or Ni, that is, the adhesive layer is formed by depositing Ti element, Cr element, Si element or Ni element on the surface of the base cloth. .. For example, a form in which magnetron sputtering technology and a titanium target are adopted and vapor deposition is performed in an argon atmosphere to form a single metal Ti layer on the surface of the base fabric.
2. The form in which the adhesive layer is an oxide layer of Ti, Cr, Si or Ni, titanium oxide, chromium oxide (chromium trioxide), silicon oxide or nickel oxide (Ni ₃ N, Ni ₃ N ₂ and Ni ₃ N _3). (Including) is vapor-deposited on the surface of the base cloth to form an adhesive layer. For example, a form in which a titanium target is used by adopting magnetron sputtering technology and oxygen is continuously injected into the coating room to form a titanium oxide layer on the surface of the base fabric.
3. The adhesive layer is a nitride layer of Ti, Cr, Si or Ni, and titanium nitride, chromium nitride, silicon nitride or nickel nitride is vapor-deposited on the surface of the base cloth to form the adhesive layer. For example, a form in which a titanium nitride layer is formed on the surface of the base fabric by continuously injecting nitrogen into the coating room at the same time as using a titanium target by adopting magnetron sputtering technology.
4. The form in which the adhesive layer is an alloy layer containing at least one of Ti, Cr, Si and Ni, for example, 316 stainless steel by adopting magnetron sputtering technology (of which, the mass content is 16.0 to 18.5). Any one of four types such as% Cr, a form using a target material having a mass content of 10.0 to 14.0% Ni, and a mass content of 1.0% or less Si) is arbitrarily selected. You can choose.

In the examples of the present disclosure, one color-developing layer may be formed on the surface of the adhesive layer, or two or more color-developing layers that gradually overlap on the surface of the adhesive layer may be formed. For example, on the surface of the adhesive layer, there are four color-developing layers, a simple substance metal magnesium layer, a simple substance metal aluminum layer, a simple substance metal copper layer, and a copper nitride layer, gradually from the back to the outside.

In particular, when there are two or more coloring layers on the surface of the adhesive layer, it is best that the two adjacent coloring layers have different configurations.

The above-mentioned adjacent coloring layers are different in composition, which means that the two coloring layers are different in composition or are not completely the same.
1. A situation in which the composition of the elements forming the coloring layer is different, for example, a situation in which the elements in the two layers are Ag and Ti, respectively.
2. Situations where the existing forms of the elements forming the color-developing layer are different, for example, it is considered that the two layers have different constituents _{of simple substances, oxides, nitrides or alloys of the same type of elements (two layers including Ti and TiO 2).} ) Can be included, respectively.

Any of the above-mentioned constitutional forms of each layer can be realized by controlling the vacuum deposition process. For example, in situation 1 above, different target materials can be selected, for example, first select a silver target to form a single metal silver layer, and then select a titanium target to form a simple metal titanium layer. .. In Situation 2, the same target material is selected but different gases are injected. For example, in vacuum deposition, titanium targets are selected both times, but the first time argon is injected into the coating chamber to form a single metallic titanium layer, and the second time oxygen is injected into the coating room to form carbon dioxide. The titanium layer is formed.

Specifically, for each color layer
1. A form in which the coloring layer is a single layer of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au or Mg.
2. A form in which the coloring layer is an oxide layer, a nitride layer or a carbide layer of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au or Mg.
3. Any one of three types of forms such as a form in which the coloring layer is an alloy layer containing at least one element of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au and Mg. Can be selected.

According to the research of the inventor, if the thickness of a certain coloring layer is simply increased while keeping other conditions unchanged, the final color of the colored fabric changes as the thickness of the coloring layer changes. Was discovered. However, when the thickness of the color-developing layer reaches a certain critical value, the wavelength band reflected by the final colored fabric shows little change. Generally, the thickness of each coloring layer is controlled to be 1 to 200 nm.

In the examples of the present disclosure, the outermost coloring layer acts to protect and isolate the coloring film layer as a whole, and is free from the influence of oxygen, water, acid, alkali, etc. in the environment on the coloring film. For the outermost coloring layer, a material having good wear resistance, antioxidant performance or acid resistance and alkali resistance is generally selected because the durability of the colored fabric can be improved. The outermost coloring layer contains at least one of Ti, Zn, Fe and Cu elements, and specifically, the composition of the elements of the outermost coloring layer is the actual requirement for textile products. Can be reasonably selected according to.

Specifically, the outermost coloring layer is
1. A form in which the outermost coloring layer is an oxide layer or a nitride layer of Ti, Zn, Fe or Cu, for example, a copper oxide layer or a copper nitride layer is adopted as the outermost coloring layer, and an actual vacuum is used. A form in which a copper target is selected and oxygen or nitrogen is injected into the coating room during vapor deposition.
2. A form in which the outermost coloring layer is an alloy layer containing at least one element of Ti, Zn, Fe and Cu, for example, a form in which a titanium-zinc alloy is used as a target material during vacuum deposition. One of the two types of forms can be arbitrarily selected.

The total number of color-developing layers and changes in the composition, thickness, and arrangement procedure of the elements of each layer all cause the final colored woven fabric to exhibit different colors, and the selectable range of the material to be the color-developing layer. It can be understood that it gives the colored woven fabric the possibility of having more colors because it becomes very wide and the arrangement method and arrangement procedure of each color-developing layer become more flexible.

At the same time, since the color of the colored woven fabric can be realized by adjusting one or several of the above elements, the dependence of the color on the thickness of the color-developing film layer is reduced, and the yield and industrial operability are improved. Greatly improve.

Of course, in some special situations, there are materials that can be both an adhesive layer and a color-developing layer at the same time. For example, when a titanium nitride layer or a titanium dioxide layer is vacuum-deposited on the surface of the base fabric, the colored fabric is given a beautiful color or a predetermined or expected color.

In addition, the wider selectable range of materials used in the embodiments of the present disclosure allows colored fabrics to have performance not found in traditional fabrics. For example, since the selectable materials are mainly metals, metal oxides, metal nitrides, and alloys, it is possible to reduce the resistivity of colored woven fabrics, and woven products having antistatic performance, that is, It is advantageous to obtain an antistatic woven fabric. Alternatively, when Ag is used in the colored layer, it also makes it possible to impart good antibacterial properties to the woven product. Alternatively, by changing factors such as the selected material, the arrangement method of the color-developing film layer, and the thickness of the arrangement, the wavelength band of the reflected light of the woven fabric can be adjusted, so that an ultraviolet protection woven fabric or an infrared protection woven fabric can be obtained. You will also be able to do it. Therefore, by adopting the coloring method provided in the examples of the present disclosure, it can be applied to the processing and preparation of woven fabric products according to special requirements.

In addition, the coloring methods provided in the embodiments of the present disclosure make the colored fabrics very resistant to discoloration, and other related performances such as antistatic performance of the colored fabrics are also common. It is superior to the colored fabrics obtained by the vacuum deposition method.

At the same time, since none of the above materials for forming the adhesive layer and the coloring layer is radioactive or toxic, the safety of the colored woven fabric is ensured.

In the examples of the present disclosure, the method for forming the adhesive layer and the color-developing layer is not particularly limited, but a suitable vacuum deposition method can be reasonably selected according to factors such as the material to be selected and the thickness of the film. , Atomic layer deposition, evaporative coating, magnetron sputtering, etc., but not limited to these. In the specific implementation process of the present disclosure, magnetron sputtering is used to form the above-mentioned adhesive layer and at least one color-developing layer on the surface of the base fabric.

Specifically, the composition of the adhesive layer and the color-developing layer is controlled by the selection of the target material and the gas (oxygen, nitrogen, argon, etc.) injected into the coating room (work room). The thickness of the adhesive layer and the coloring layer is controlled by controlling conditions such as power, target base distance, vehicle speed, and gas flow in the magnetron sputtering process. It also adjusts the thickness of the color-developing film layer by controlling the instantaneous power change, which allows different colors to be in different positions on the same fabric, making the fabric richer as there is a gradation color. become.

In the specific implementation process of the present disclosure, the power in magnetron sputtering can be reasonably set according to the situation of the target material used. Generally, the target base distance is 2 to 20 cm, the vehicle speed is 0.5 to 10 m / min, the background vacuum (background vacuum) is 4.0 x ^10-3 Pa or less, and the working vacuum is 2.0. It is controlled to × 10 ^{-1 Pa or less.} By magnetron sputtering completed under the above conditions, a colored woven fabric having good performance can be obtained.

The above-mentioned vehicle speed refers to the moving speed of the base fabric and is one of the factors that influence the thickness of the vapor deposition. It can be understood that by rationally controlling the vehicle speed, the thickness of the film to be deposited can be made more uniform, and in general, the vehicle speed is controlled to 0.5 to 5 m / min. By doing so, continuous production of woven fabric coloring can be realized and the production rate can be secured, and at the same time, the thickness of the film can be ensured to be uniform, and the final coloring can be achieved. Make the fabric color relatively uniform.

The inventor has traditionally limited fabric coloring by vacuum deposition technology to a few special fibers such as polyimides and carbon fibers, and as a result of researching and analyzing the locality that does not apply to traditional fibers. In the case of traditional fiber, plant fibers such as linen, and synthetic fibers such as polyester and spandex, the cause is high in the vacuum deposition process, while the water content of some of the above special fibers themselves is low. It is considered that the impact of the energy particles causes the gas in the base cloth to escape to form a gas layer, hinder the deposition of the film layer, and finally deteriorate the discoloration resistance.

Based on the above findings and analysis, the inventor has tried multiple drying processes, such as the traditional hot air drying process in the dyeing and finishing industry, or the dehydration process with glass, PE coating, and the moisture and ammonia of the base fabric. I was trying to take such things thoroughly. However, since the coloring mechanism of the traditional dyeing and finishing industry and the coloring mechanism by vacuum deposition are completely different, in the traditional dyeing and finishing industry, the drying treatment of the base fabric is performed by using hot air, and the strength of the yarn and the strength of the yarn are increased. The purpose is to improve the fluffiness, but there is no obvious advantage in the discoloration resistance of the fabric. In the case of matrix materials that do not contain water and gas, such as glass and PE, there is no gas layer formed by the escape of water and gas during the coating process, and the isopropanol dehydration process commonly used in glass coating is also large for textiles. Causes damage. The discoloration resistance of the colored woven fabric does not meet the standard requirement even if it is dried by ordinary heating.

Radiation drying is an emerging drying technology in the field of agricultural production. Specifically, it is a method of using electromagnetic waves such as infrared rays and microwaves as a heat source and sending heat by radiation to a material to be dried for drying. The inventor has introduced a radiant drying technique into the field of textile coloring to effectively remove moisture and gas (such as ammonia) in the base fabric, and in the subsequent vacuum deposition process, the moisture or ammonia inside the fibers. The gas layer formed by the emission is free from the effect on the discoloration resistance of the colored fabric, and not only the discoloration resistance of the colored fabric reaches the relevant standard requirements, but also the said for various fibers. The adaptability of the coloring technique will also be good.

The drying by radiation may be specifically drying by infrared radiation. For example, an infrared radiation lamp or an infrared radiation lamp group can be used to illuminate the base cloth or to be dried by microwaves. In the specific implementation process of the present disclosure, a microwave drying method is adopted, microwaves having a frequency of 2.45 GHz ± 25 MHz are selected, and the drying temperature is set to 200 ° C. or lower. Microwave drying may be completed in an atmospheric environment (normal pressure environment) or a vacuum environment.

The temperature of the above microwave drying should be slightly lower than the temperature resistance T of the woven fabric. For example, it can be understood that the temperature resistance of the woven fabric (T-10) ° C. or lower is set to avoid the embrittlement phenomenon of the fibers. The corresponding drying temperature can be reasonably set by the base fabric.

In addition, compared to the traditional drying method that uses hot air drying or electric drying, the microwave drying method has the advantages of short time, low energy consumption, no pollution, uniform drying, etc. Can't do damage.

Further, before the vacuum deposition described above, the base cloth after drying by radiation can be subjected to vacuum heat treatment, and generally, the heating temperature is 60 to 120 ° C. and the pressure is 3.0 ×. It is controlled to less than ^{10-3 Pa.} By carrying out the above vacuum heat treatment, moisture and gas, especially surface moisture and gas, are further removed, the woven fabric is prevented from reciprocating, and the adhesive force between the base fabric and the adhesive layer and the coloring layer is improved. can do.

Generally, in the process of drying and heating the base fabric, the moving speed of the base fabric is controlled to be the same as the vehicle speed in the subsequent vacuum deposition to realize continuous and smooth production of the entire coloring process. Can be done.

Specifically, the above-mentioned textile coloring process may be completed on a vacuum deposition production line. According to the procedure of the production flow, the production line has one rewinding chamber, one radiant drying chamber, one vacuum heating chamber, one or more serially connected coating chambers (working chambers) and one winding chamber. include. The production line may also include transmissions and may employ transmissions used in traditional dyeing and finishing processes, or based on the actual conditions of the rewinding chamber, coating room and winding chamber. It may be adjusted adaptively.

Among them, the function of the rewinding chamber is to store various soft base fabrics in this chamber, start the conveyor belt by the action of the guide roller, and transmit the base fabric to the back coating room. The rewinding chamber may be in a normal pressure environment or a vacuum environment.

The radiant drying chamber is for carrying out a radiant drying process, and is provided with an infrared radiating device or a microwave radiating device. In the specific implementation process of the present disclosure, a microwave emitting device is usually used, and in general, 2.45 GHz ± 25 MHz is selected as the microwave frequency, and the drying temperature is set to 200 ° C. or lower. There is. The radiant drying chamber can communicate directly with the atmosphere, or a vacuum exhaust device can be provided as a set to achieve a vacuum environment.

The vacuum heating chamber is for performing a vacuum heating treatment on the base cloth after drying by radiation. Generally, a heating device such as a baking unit and a vacuum exhaust device are internally installed in the vacuum heating chamber. With this, the temperature in the vacuum heating chamber is maintained to be 60 to 120 ° C., and the degree of vacuum becomes 3.0 × 10 ⁻³ Pa or less.

The function of the coating room is to form an adhesive layer and a coloring layer on the surface of the base fabric. Install the corresponding target material in each coating room as required by the coating process. In general, a separate gas passage is provided in the coating room to inject a reaction gas such as oxygen or nitrogen, or a protective gas such as argon.

After the vacuum deposition is completed, the base cloth is stored in the take-up room from the coating room and is taken up as the guide roller rotates, so that the entire coloring process is completed.

As a special explanation, when vacuum deposition is performed in a coating room, the purity of the target material used is generally 99. Since the purity of the target material used cannot reach absolute 100%. It is 99%. In the examples of the present disclosure, unavoidable impurities in the target material are ignored. For example, if the target material used is a titanium target and the gas injected into the coating chamber is argon, it is considered that a single metallic titanium layer is formed by vacuum deposition.

Further, a mask transmission device can be arranged in the above-mentioned vacuum deposition production line so as to simultaneously realize the pattern dyeing at the same time as coloring the woven fabric and further improve the efficiency of woven fabric coloring.

In addition, the surface of the base fabric can be pretreated before it is loaded into the vacuum deposition production line, specifically, it is cleaned to stain, oil stain, other impurities, etc. on the base fabric. Should be removed.

The coloring method provided in the examples of the present disclosure does not require the base fabric to meet the requirements of traditional dyeing processes with respect to hair effect, whiteness, pH value, glossiness, etc. The corresponding pretreatment process to meet the requirements is no longer required, and the prefinishing part does not require purification or mercerizing, so the pretreatment process or part and the resulting energy, water consumption and chemistry. Significantly reduce material consumption and wastewater problems.

Colored fabrics obtained from vacuum-deposited production lines may be further post-finished, primarily using physical finishing methods to achieve the softness of clothing, apparel and other fabrics. Let me do it. This process can be referred to as the post-finishing process of the traditional dyeing and finishing process and will not be described repeatedly.

In the examples of the present disclosure, a further colored woven fabric is provided, which is obtained by coloring the surface of the base fabric by adopting the above-mentioned coloring method.

The base cloth for coloring may be a natural fiber such as shavings or linen, or a synthetic fiber such as polyester or spandex. In the examples of the present disclosure, there is no particular limitation here. In particular, the base fabric may also be high-performance fibers such as carbon fibers, polyimides, and glass fibers that are less likely to be dyed with traditional chemical industrial dyes.

The knitting method of the base fabric may be knitting, tatting, or another knitting method, and is not particularly limited in the examples of the present disclosure.

As described above, the colored woven fabric prepared by adopting the coloring method provided in the examples of the present disclosure has a richer color and better discoloration resistance, and at the same time, realizes mass production by industrialization. You can also do that.

At the same time, the colored woven fabric has the same breathability and moisture permeability as ordinary woven fabrics, and at the same time, has characteristic points not found in traditional woven fabrics, such as antistatic performance, UV radiation protection, waterproof performance and antibacterial properties. The prospect of application is wider because it can also be equipped with.

The woven fabric coloring method provided in the examples of the present disclosure has the following advantages.

1. By adopting vacuum vapor deposition technology, an adhesive layer and a coloring layer are formed on the surface of the base fabric, and the woven fabric is colored by utilizing the absorption, refraction and reflection action of different materials and different thickness nano film layers against light. The effect is achieved, and by selecting different materials, changing the arrangement means of each film layer and the thickness of each film layer, the fabric is made to exhibit different colors, and the richness of color. Is greatly improved.

2. When this coloring method is adopted, the color of the woven fabric can be adjusted or changed by selecting the material or the means of arranging the film layer, so that the color sensitivity and dependence on the thickness of the film layer are greatly reduced. Therefore, industrial operability and feasibility are also improved.

3. With this coloring technology, the colored fabric can have very good discoloration resistance, such as discoloration resistance to water (GB / T5713-2013) and discoloration resistance to sweating (GB / T3922-2013). ), Discoloration resistance to friction (GB / T3920-2008), discoloration resistance to soaping (GB / T3921-2008), discoloration resistance to dry cleaning (GB / T5711-1997), discoloration resistance to light (GB / The discoloration resistance including T8427-2008) has reached level 4 or level 4 to level 5, and meets the regulations of GB / T2660-2017 "shirt" standard for first-class products.

4. This coloring technology has very strong universal adaptability and can be applied to special fiber fabrics including high-performance fibers that cannot be colored by traditional dyes, and traditional natural fibers and synthetic fiber fabrics. At the same time that it is not necessary to design different coloring means for different base fabrics, the coloring technology is also very universally adaptable to different knitting methods, so it is a set of equipment for different knitting methods. Further improve industrial operability and feasibility by eliminating the need to design.

5. By adopting this coloring technology, the colored woven fabric obtained will not only have the same breathability and moisture permeability as ordinary woven fabrics, but also the colored woven fabric will be made of the material used in this coloring technology. , It will be possible to have unique performance that traditional textiles do not have. for example,
(1) By applying the film layer to this coloring technique to develop color, it is possible to significantly reduce the tip discharge effect of the woven fabric by utilizing the covering performance of the film layer on the woven fiber, and the metal layer of the film layer. Due to the conductive effect appointed by, the static electricity of the woven fabric can be further reduced. Therefore, this color-developing technology can improve the antistatic effect of the woven fabric and can also fulfill the electromagnetic shielding function.
(2) The color-developing film layer according to the present technology can enhance absorption and reflection of light waves to an ultraviolet area or an infrared area by a rational design, and can perform a sunburn prevention function or a certain degree of infrared shielding function.
(3) Due to the compactness and hydrophobic effect of the surface layer of the color-developing film, a good waterproof effect can be given to the fabric.

6. In the entire coloring process, by applying a mask that moves in synchronization with the cloth, it is possible to realize synchronous pattern dyeing and dyeing, and the production process can be significantly reduced.

7. With this coloring technique, the base fabric is not required to meet the requirements of the traditional dyeing process regarding hair effect, whiteness, pH value, glossiness, etc., and even in the pre-finishing part, purification and mercerizing Since it does not require processing and only removes oil, deglues, and cleans, it significantly increases the problems of pretreatment processes and parts, and the energy consumption, water consumption, chemical substance consumption, and waste water that arise from them. To reduce to.

8. The entire coloring process is done without water and without chemicals, which saves a lot of water resources compared to traditional dyeing techniques and emits waste liquid, hedro and poisonous gas during production. It has the advantage of being environmentally friendly because it does not.

The colored fabrics provided in the embodiments of the present disclosure are richer in color and can also be produced and obtained by industrialization.

In addition, the colored woven fabric basically has the same breathability and breathability as ordinary woven fabrics, so that it can satisfy the current usage scene of traditional woven fabrics. At the same time, the colored woven fabric can also have characteristic points not found in traditional woven fabrics, such as antistatic performance, UV radiation protection, waterproof performance and antibacterial properties, so that the prospect of application becomes wider. ing.

It is a light reflection spectrum of the colored woven fabric provided in Examples 1 to 3 of the present disclosure. It is a photograph of the surface of the colored fabric provided in Example 1 of the present disclosure. It is a photograph of the surface of the colored fabric provided in Comparative Example 1 of the present disclosure.

In order to further clarify the purpose, technical solutions and advantages of the embodiments of the present disclosure, the technical solutions of the embodiments of the present disclosure will be described in a clear and complete manner and, of course, explained below. The examples are only a part of the examples of the present disclosure.

In the following examples, the process of coloring the fabric generally includes pretreatment (surface cleaning), radiant drying treatment, vacuum heating, vacuum deposition, post-finishing, testing, detection, finished product, of which
The pretreatment is specifically to wash the base fabric with deionized water and perform initial drying with heat to ensure that the base fabric surface is clean.

When radiant drying, vacuum heating and vacuum vapor deposition are completed in a vacuum vapor deposition production line and the production flow procedure is followed, the production line has one unwinding chamber, one radiant drying chamber, one vacuum heating chamber and one. Alternatively, it includes a plurality of coating rooms (work rooms) and one winding room. The production line also includes transmissions, using transmissions used in traditional dyeing and finishing, where semi-finished fabrics or colored fabrics are gradually radiated from the unwinding chamber to the radiant drying chamber. It is allowed to pass through the vacuum heating chamber and the coating chamber to reach the winding chamber.

The rolled base cloth is first dried by radiation to remove water and gas from the base cloth, then passed through a vacuum heating chamber to remove water and gas from the surface of the base cloth, and then heated twice as described above. After the treatment, the adhesive force between the base fabric and the adhesive layer and the color-developing layer becomes better.

Depending on the actual requirements, one or more target materials are placed in each coating room (working room), and in the magnetron sputtering process, a corresponding film is gradually formed on the surface of the base fabric according to the number of the target material. For example, four types of target materials are arranged in one coating room, and they are described as target material 1, target material 2, target material 3, and target material 4, respectively. In this way, magnetron sputtering is gradually performed according to the above procedure. A four-layer film can be obtained.

The post-finish can be rationally selected according to the actual situation of the colored fabric, and the softness of the fabric mainly for clothing and apparel is adjusted by adopting a method such as physical finishing. This is achieved, but for other types of colored fabrics, no post-finishing process is required unless there are special requirements.

The colored fabric can be post-finished and then passed a series of tests and detections to complete the entire production flow and give the final finished product.

Comparative Example 1

In this comparative example, a method of coloring the woven fabric is provided, and the base fabric used is completely consistent with Example 1. The only distinction between the coloring method and Example 1 is that the base fabric was not dried by microwaves.

After the above processing, a part of the finally obtained colored woven fabric becomes yellowish green. FIG. 3 is a photograph of the surface of the colored woven fabric. From FIG. 3, the film layer is not vapor-deposited in a part of the colored woven fabric, and is expressed as the original color of the base fabric. It is divided that non-uniformity is expressed.

As a result of performing a discoloration resistance test on the area where the film layer is vapor-deposited, the discoloration resistance is only level 1 to level 2, and GB / T2660-2017 "shirt" for the accepted product (passed at level 3). It has not reached the standard regulation.

From Example 1 and Comparative Example 1, it is divided that by performing the drying treatment with microwaves on the base cloth, the film layer deposited on the surface of the base cloth becomes more uniform and the discoloration resistance is significantly improved. Be done.

Example 2

In this embodiment, a method for coloring a woven fabric is provided, the base fabric used is polyester, the knitting method is tatting, and specific processing steps are shown in Table 2 below.

The colored fabric finally obtained after the above processing has a reddish-brown color, and the reflection spectrum within the wavelength range of 200 to 2000 nm is shown in FIG.

As a result of performing a discoloration resistance test on the colored woven fabric according to this example, discoloration resistance to water (GB / T5713-2013), discoloration resistance to sweating (GB / T3922-2013), and discoloration resistance to friction Properties (GB / T3920-2008), discoloration resistance to soaping (GB / T3921-2008), discoloration resistance to dry cleaning (GB / T5711-1997), discoloration resistance to light (GB / T8427-2008), etc. It can be divided that the discoloration resistance including reaches level 4 or level 4 to level 5 and meets the regulation of GB / T2660-2017 "shirt" standard for first-class products.

A series of detections such as UV protection, breathability, surface water repellency, and water permeability are performed on the colored fabric, and the red-brown fabric obtained by the traditional dyeing method is used as a control, and the related test items and tests are used. The results of are shown in Table 3 below.

The test for surface water repellency is performed by selecting and testing three samples of parallel woven fabrics, which are referred to as Sample 1 #, Sample 2 # and Sample 3 #, respectively.

According to the comparison results of the tests in Table 3, the colored fabric according to this example is clearly superior to the fabric obtained by the traditional dyeing method in terms of UV protection performance, water repellency and water resistance. In terms of breathability and breathability, the test results of both are almost the same.

Therefore, adopting the coloring method according to the present embodiment does not affect the performance such as breathability and moisture permeability of the final colored woven fabric, and the colored woven fabric has unique performance, for example, UV protection performance. , Water repellent effect and water resistance are given.

Example 3

In this embodiment, a method for coloring a woven fabric is provided, the base fabric used is glass fiber, the knitting method is tatting, and specific processing steps are shown in Table 4 below.

A series of detections of antistatic performance are performed on the colored woven fabric, and two kinds of fabrics are provided for comparison, of which a white woven fabric (glass fiber) is adopted as the comparative fabric 1 and the comparative fabric 2 is used. The only difference between the processing process and the above glass fiber is that the base fabric was not dried by microwaves.

The test items and test results related to the above three types of dough are shown in Table 5 below.

From the test results in Table 5, it can be classified that the colored fabrics obtained in this example have clearly lower charging voltage and surface resistivity due to friction than the comparative fabrics. As a result, it can be seen that the colored woven fabric obtained by adopting the coloring method according to the present embodiment has excellent antistatic performance.

As can be observed with the naked eye, the film layer deposited on the surface of the colored fabric obtained in this example is very uniform, and the color is also relatively uniform, but the film is formed in a part of the comparative fabric 2. There is no layer deposition and the color differences in different areas are relatively clear.

Lastly, each of the above embodiments is for the purpose of explaining the technical solution of the present disclosure, and is not intended to limit the present invention. However, those skilled in the art may still modify the technical solutions described in each of the above embodiments, or make equivalent substitutions for some or all of the technical features thereof. However, it should be understood that these modifications or substitutions do not deviate from the essence of the corresponding technical solution within the scope of the technical solution of each embodiment of the present disclosure.

The present application relates to a woven fabric coloring technique, and specifically relates to a woven fabric coloring method and a colored woven fabric.

In conventional color system, when thus distinguished color principle, there are mainly two types of chromogenic method of dye color and structural color. The color of the dye depends mainly on the chemical bonds in the substance molecule, and while the electrons in some chemical bonds tend to absorb visible light of a specific wavelength, the remaining other wavelengths are reflected and differ. It is designed to be presented as a color. A substance capable of achieving such an effect is a pigment, and such a color is called a pigment color. The color of the dye can be understood as one unique property of the material.

Structural color , also called physical color, is a special structure on the surface of an object that causes light waves to be refracted, diffusely reflected, diffracted, or interfered with to change the composition of light, resulting in light. While increasing the light intensity of a part of a particular wavelength in the spectrum, part of it becomes weaker and eventually the object exhibits a different color. Metallic luster and light on the surface of the beetle's body wall are typical structural colors .

Traditional coloring of woven fabrics mainly depends on the color development by the color of the dye, specifically, dyeing with a dye for the chemical industry, and is mainly generated by giving the dye to the base fabric. Currently, the dyeing and finishing industry-wide dyeing and finishing process generally involves steps such as pretreatment, dyeing, pattern dyeing and finishing. However, the following drawbacks are apparent in traditional dyeing methods.
1. The dyeing and finishing industry belongs to the industry that is currently strictly regulated in Japan, and the amount of water consumed for dyeing cloth per 100 meters is 2 to 4 tons, and the amount of wastewater in the total water consumption is It is 60 to 80%. At the same time, the drawback is that both volatile pollutants are being produced during the preparation and production of dyes.
2. Dyeing with conventional chemical industrial dyes mainly relies on adsorption and fixation between the dyeing group and the textile fibers, but the process is very dependent on the fiber structure and therefore different fabrics. In the case of fabrics, they need to be used in combination with different dyes and auxiliaries, for example nylon fabrics mainly use acidic dyes and acrylic fabrics mainly use cationic dyes or disperse dyes. The acetate fiber woven fabric mainly uses disperse dyes, but it is sometimes dyed with insoluble azo dyes, so it has the disadvantage that the universal adaptability of pigments is inferior.
3. Traditional dyeing is mainly done with liquid dyeing agents, and there is a big difference in the degree of shrinkage and curling of woven fabrics due to different knitting methods, so the equipment used for dyeing woven fabrics with different knitting methods is also different. The drawback.

Given the presence of the above defects in traditional chemical dyeing, how to effectively construct structural colors with textile materials has already been the focus and research of the textile dyeing and finishing industry. It is a target . For example, using magnetron sputtering technology, radio frequency sputtering is performed on a woven fabric base (base cloth) to form a periodic film alternating _{with SiO 2} and TiO _{2 on the surface of the base cloth.} When illuminated by light, the colored fabrics become bright and vibrant. The coloring technique mainly utilizes the interference of light generated by alternately and periodically arranging a _{SiO 2} film having a low refractive index and a TiO _{2 film having a high refractive index to make a colored fabric bright and vivid.} It is made to exhibit a unique color.

Since the above coloring technology eliminates the discharge of waste water, waste of water resources and pollution to the environment are avoided, and at the same time, the adaptability to the base cloth is widened, and the fibers of the base cloth are natural such as mulberry silk. It may be a protein fiber or a chemical fiber such as polyester or nylon. However, since it is a coloring technology that realizes color development by using the periodic interference action of only two types of film layers, titanium dioxide and silica, with respect to light, the types of colors to be finally presented are greatly limited, and the film is also limited. With this coloring technique, which is extremely sensitive to the thickness of, it is very difficult to achieve the ideal yield in actual production, so the spread of industrialization by the coloring technique is greatly limited. In addition, the discoloration resistance of the woven fabric by the coloring technique cannot be guaranteed.

Currently, a method of slightly increasing the color richness by depositing other metal units or alloys on the fiber surface using vacuum vapor deposition technology has been reported in a small amount of literature, but the method is carbon fiber. It is limited to the coloring of a few special fibers such as polyimide and does not apply to traditional cotton , silk and other fibers. This is reflected in the discoloration resistance, which does not meet national standards, mainly because the colored fabrics are not uniformly colored and there is no film deposition in some areas.

Thus, not only does the fabric produce a rich color, but the resulting colored fabric has very good discoloration resistance, while at the same time satisfying the production requirements of the industry, universal for textile fibers. to develop a good coloring method adaptive is currently the problem urgently solved is awaited.

In response to the above defects, the embodiments of the present disclosure provide a method for coloring a woven fabric, which not only produces a rich color but also reduces the sensitivity of the color to the thickness of the film layer, and is therefore industrial. Improve operability. At the same time, the universal adaptability of the coloring method to the fibers is improved, and it is possible to make the colored woven fabric have excellent discoloration resistance.

In the embodiments of the present disclosure, a colored woven fabric prepared by the above-mentioned coloring method is also provided, and the colored woven fabric is not only provided with rich color and good discoloration resistance, but also prepared by an industrialized method. You can also get it.

In order to achieve the above object, in the embodiment of the present disclosure, a method for coloring a woven fabric is provided, and the method is described.
Steps to perform a radiative drying process on the base fabric,
By vacuum evaporation, and a step of successively forming a colored layer of the contact adhesive layer and at least one layer in the base fabric surface after drying by radiation, however,
Ti in the structure of the adhesive layer, Cr, contains at least one of Si and Ni elements, whose thickness is to be a 1～2000Nm,
Al to the configuration of the color-forming layer, Ti, Cu, Fe, Mo , Zn, Ag, at least one is included among Au and Mg element, the total thickness of the coloring layer is 1～4000Nm, preferably, 4 Includes a step of making it ~ 2000 nm.

According coloring method provided in the embodiment of the present disclosure, the application of vacuum deposition techniques to form a colored layer that contains the adhesive layer and coloring layer in the base fabric surface, due to the nano-layer of different materials and different thicknesses Utilizing the combined action of light absorption, reflection, refraction, etc., the resulting colored fabric is made to exhibit different colors.

In addition, if the materials used for the adhesive layer and the coloring layer, the thickness of each film layer, and the arrangement method of the film layers are changed, the color of the colored woven fabric will change accordingly. Gives the possibility of richer colors and more colors. Therefore, by appropriately adjusting and arranging at least one of the above elements according to the required color of the woven fabric, the dependence of the color of the woven fabric on the thickness of the film layer can be significantly reduced. This is advantageous for the realization of the textile coloring industry.

At the same time, by the coloring method, a colored woven fabric including discoloration resistance to water, discoloration resistance to sweating, discoloration resistance to friction, discoloration resistance to soaping, discoloration resistance to dry cleaning, discoloration resistance to light, etc. discoloration resistance are both reached level 4 or level 4 level 5, first quality, further GB / T2660 for excellent grade - meets 2017 "shirt" requirements of the standard.

According to the research of the inventor, the coloring method for the base cloth fiber has good adaptability, and the base cloth fiber for coloring may be a carbon fiber which is difficult to be dyed with a traditional chemical industry dye, and is synthesized such as polyimide. It has been discovered that it may be a fiber, a synthetic fiber such as polyester, nylon, spandex, which is commonly found today , or a natural fiber such as traditional cotton, linen, silk.

In addition, the coloring method is highly adaptable to the knitting method of the base fabric, and the base fabric obtained by knitting or tatting can be colored by using the above coloring method and is resistant to discoloration. Is good.

Based on the above phenomenon, the inventor relies mainly on high-energy bonding formed by the color-developing film layer and the base cloth with the cooperation of high-energy ions, and this type of bonding is the main cause of the occurrence. Because it is affected by the strength of the surface energy of the base fabric and the ease of atom transfer in the adhesive layer, and is not sensitive to the fiber type and knitting method of the base fabric, the coloring method uses different base fabrics and knitting methods. It was analyzed that the shift is also applied to different base fabrics.

The coloring equipment used in combination with the coloring method provided in the embodiments of the present disclosure is also highly universally adaptable, eliminating the need to design corresponding dyeing equipment for base fabrics with different knitting methods. Therefore, it is not difficult to understand that it further improves industrial operability.

According to the technical solution according to the embodiment of the present disclosure, the adhesive layer is for improving the adhesive force between the surface of the base fabric and the color-developing layer. Specifically, for the adhesive layer, elements such as Ti, Cr, Si, and Ni, which generally have good diffusion performance, can be selected. In the specific implementation process of the embodiment of the present disclosure , the adhesive layer can be arbitrarily selected from one of the following four types.
1. The adhesive layer is a single layer of Ti, Cr, Si or Ni, that is, the adhesive layer is formed by depositing Ti element, Cr element, Si element or Ni element on the surface of the base cloth. It, for example, using a magnetron sputtering technique and titanium target was deposited in an argon atmosphere, so to form a simple metal Ti layer with the base fabric surface morphology.
2. The form in which the adhesive layer is an oxide layer of Ti, Cr, Si or Ni, titanium oxide, chromium oxide (chromium trioxide), silicon oxide or nickel oxide (Ni ₃ N, Ni ₃ N ₂ and Ni ₃ N _3). for example I form der to form the adhesive layer includes) was deposited on the base fabric surface, using a magnetron sputtering technique injected simultaneously continuously oxygen using titanium target into the coating room, with the base fabric surface A form that forms a titanium oxide layer .
3, the adhesive layer is Ti, Cr, form a nitride layer of Si or Ni, titanium nitride, chromium nitride, I form der the silicon nitride or nitride of nickel was deposited on the base fabric surface to form an adhesive layer, For example, a form in which a titanium target is used by using magnetron sputtering technology and nitrogen is continuously injected into the coating room to form a titanium nitride layer on the surface of the base cloth .
4. The form in which the adhesive layer is an alloy layer containing at least one of Ti, Cr, Si and Ni, for example, 316 stainless steel using magnetron sputtering technology (provided that the mass content is 16.0 to 18.5). % of Cr, mass content of 10.0 to 14.0% of Ni, the mass content of 1.0% or less of Si) form state in which a target material.

In the embodiment of the present disclosure, one color-developing layer may be formed on the surface of the adhesive layer, or two or more color-developing layers that gradually overlap on the surface of the adhesive layer may be formed. For example, on the surface of the adhesive layer, there are four color-developing layers, a simple substance metal magnesium layer, a simple substance metal aluminum layer, a simple substance metal copper layer, and a copper nitride layer, gradually from the back to the outside.

In particular, when there are two or more coloring layers on the surface of the adhesive layer, it is best that the two adjacent coloring layers have different configurations.

The above and configuration of the adjacent coloring layers are different, color-forming layer of the two layers, refers to configurations differ or not completely the same,
1. A situation in which the composition of the elements forming the coloring layer is different, for example, a situation in which the elements in the two layers are Ag and Ti, respectively.
2. Situations where the existing forms of the elements forming the color-developing layer are different, for example, it is considered that the two layers have different constituents _{of simple substances, oxides, nitrides or alloys of the same type of elements (two layers including Ti and TiO 2).} ) Can be included, respectively.

Any of the above-mentioned constitutional forms of each layer can be realized by controlling the vacuum deposition process. For example, in situation 1 above, different target materials can be selected, for example, first select a silver target to form a single metal silver layer, and then select a titanium target to form a simple metal titanium layer. .. In Situation 2, the same target material is selected but different gases are injected. For example, in vacuum deposition, titanium targets are selected both times, but the first time argon is injected into the coating chamber to form a single metallic titanium layer, and the second time oxygen is injected into the coating room to form carbon dioxide. The titanium layer is formed.

Specifically, one of the following three types of forms can be arbitrarily selected for each color development layer.
1. A form in which the coloring layer is a single layer of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au or Mg.
2. A form in which the coloring layer is an oxide layer, a nitride layer or a carbide layer of Al, Ti, Cu, Fe, Mo, Zn, Ag, Au or Mg.
3, coloring layer Al, Ti, Cu, Fe, Mo, Zn, Ag, shape state is at least one alloy layer elements containing one of Au and Mg.

According to the research of the inventor, if the thickness of a certain coloring layer is simply increased while keeping other conditions unchanged, the final color of the colored fabric changes as the thickness of the coloring layer changes. Was discovered. However, when the thickness of the color- developing layer reaches a certain seaside value , the wavelength band reflected by the final colored fabric shows almost no change. Generally, the thickness of each coloring layer is controlled to be 1 to 200 nm.

In the embodiments of the present disclosure, the outermost color-developing layer acts to protect or isolate the color-developing film layer as a whole, and is free from the influence of oxygen, water, acid, alkali, etc. in the environment on the color-developing film. For the outermost coloring layer, a material having good wear resistance, antioxidant performance or acid resistance and alkali resistance is generally selected because the durability of the colored fabric can be improved. The outermost coloring layer contains at least one of Ti, Zn, Fe and Cu elements, and specifically, the composition of the elements of the outermost coloring layer is the actual requirement for textile products. Can be reasonably selected according to.

Specifically, the outermost coloring layer can be arbitrarily selected from one of the following two types.
1. A form in which the outermost coloring layer is an oxide layer or a nitride layer of Ti, Zn, Fe or Cu, for example, a copper oxide layer or a copper nitride layer is used as the outermost coloring layer, and an actual vacuum is used. A form in which a copper target is selected and oxygen or nitrogen is injected into the coating room during vapor deposition.
2. A form in which the outermost coloring layer is an alloy layer containing at least one element of Ti, Zn, Fe and Cu, for example, a form in which a titanium-zinc alloy is used as a target material during vacuum deposition.

The total number of color-developing layers and changes in the composition, thickness, and arrangement procedure of the elements of each layer all cause the final colored woven fabric to exhibit different colors, and the selectable range of the material to be the color-developing layer. It can be understood that it gives the colored woven fabric the possibility of having more colors because it becomes very wide and the arrangement method and arrangement procedure of each color-developing layer become more flexible.

At the same time, since the color of the colored woven fabric can be realized by adjusting one or several of the above elements, the dependence of the color on the thickness of the color-developing film layer is reduced, and the yield and industrial operability are improved. Greatly improve.

Of course, in some special situations, there are materials that can be both an adhesive layer and a color-developing layer at the same time. For example, when a titanium nitride layer or a titanium dioxide layer is vacuum-deposited on the surface of the base fabric, the colored fabric is given a beautiful color or a predetermined or expected color.

Also, since the selectable range of materials used in the embodiments of the present disclosure is wider, it is possible to ensure that the colored woven fabric has performance not found in traditional woven fabrics. For example, since the selectable materials are mainly metals, metal oxides, metal nitrides, and alloys, it is possible to reduce the resistivity of colored woven fabrics, and woven products having antistatic performance, that is, It is advantageous to obtain an antistatic woven fabric. Alternatively, when Ag is used in the colored layer, it also makes it possible to impart good antibacterial properties to the woven product. Alternatively, by changing factors such as the selected material, the arrangement method of the color-developing film layer, and the thickness of the arrangement, the wavelength band of the reflected light of the woven fabric can be adjusted, so that an ultraviolet protection woven fabric or an infrared protection woven fabric can be obtained. You will also be able to do it. Therefore, the use of coloring method provided in the embodiment of the present disclosure can be applied to the processing and preparation of textile products to meet the special requirements.

In addition, the coloring method provided in the embodiments of the present disclosure corresponds to a very high discoloration resistance of the colored woven fabric, and other related performances such as antistatic performance of the colored woven fabric are also ordinary. It is superior to the colored fabrics obtained by the vacuum deposition method.

At the same time, since none of the above materials for forming the adhesive layer and the coloring layer is radioactive or toxic, the safety of the colored woven fabric is ensured.

The embodiment of the present disclosure does not particularly limit the method for forming the adhesive layer and the color-developing layer, but a suitable vacuum deposition method can be reasonably selected according to factors such as the material to be selected and the thickness of the film. , Atomic layer deposition, evaporative coating, magnetron sputtering, etc., but not limited to these. In the specific implementation process of the present disclosure, magnetron sputtering is used to form the above-mentioned adhesive layer and at least one color-developing layer on the surface of the base fabric.

Specifically, the composition of the adhesive layer and the color-developing layer is controlled by the selection of the target material and the gas (oxygen, nitrogen, argon, etc.) injected into the coating room (work room). The thickness of the adhesive layer and the coloring layer is controlled by controlling conditions such as power, target base distance, transmission speed, and gas flow in the magnetron sputtering process. It also adjusts the thickness of the color-developing film layer by controlling the instantaneous power change, which allows different colors to be in different positions on the same fabric, making the fabric richer as there is a gradation color. become.

In the specific implementation process of the present disclosure, the power in magnetron sputtering can be reasonably set according to the situation of the target material used. Generally, the target base distance is 2 to 20 cm, the transmission speed is 0.5 to 10 m / min, the background vacuum (background vacuum) is 4.0 × 10 ^-3 Pa or less, and the working vacuum is 2. It is controlled to 0 × 10 ^{-1 Pa or less.} By magnetron sputtering completed under the above conditions, a colored woven fabric having good performance can be obtained.

The above transmission speed refers to the moving speed of the base fabric and is one of the factors that influence the thickness of the vapor deposition. It can be understood that by rationally controlling the transmission rate , the thickness of the film to be deposited can be made more uniform . Generally, the transmission speed is controlled to 0.5 to 5 m / min, so that continuous production of textile coloring can be realized and the production rate can be secured, and at the same time, the thickness of the film can be increased. It can also be ensured to be uniform, ensuring that the color of the final colored fabric is relatively uniform.

The inventor has traditionally limited fabric coloring by vacuum deposition technology to a few special fibers such as polyimides and carbon fibers, and as a result of researching and analyzing the locality that does not apply to traditional fibers. In the case of traditional plant fibers such as cotton and linen, and synthetic fibers such as polyester and spandex, while the water content of some of the above special fibers themselves is low, the vacuum deposition process is high. It is considered that the impact of the energy particles causes the gas in the base cloth to escape to form a gas layer, hinder the deposition of the film layer, and finally deteriorate the discoloration resistance.

Based on the above findings and analysis, the inventor has tried multiple drying processes, such as the traditional hot air drying process in the dyeing and finishing industry, or the dehydration process with glass, PE coating, and the moisture and ammonia of the base fabric. I tried to take and thoroughly. However, since the coloring mechanism of the traditional dyeing and finishing industry and the coloring mechanism by vacuum deposition are completely different, in the traditional dyeing and finishing industry, the drying treatment of the base fabric is performed by using hot air. This is for the purpose of improving the strength and bulkiness of the yarn, but there is no obvious advantage in the discoloration resistance of the woven fabric. In the case of matrix materials that do not contain water and gas, such as glass and PE, there is no gas layer formed by the escape of water and gas during the coating process, and the isopropanol dehydration process commonly used in glass coating is also large for textiles. Causes damage. The discoloration resistance of the colored woven fabric does not meet the standard requirement even if it is dried by ordinary heating.

Radiation drying is an emerging drying technology in the field of agricultural production. Specifically, it is a method of using electromagnetic waves such as infrared rays and microwaves as a heat source and sending heat by radiation to a material to be dried for drying. Inventors, drying technology by radiation introduced into the textile coloring areas, group (such as ammonia) moisture and gas in the fabric can be effectively eliminated, and in a subsequent vacuum deposition process, the internal fiber moisture or ammonia The gas layer formed by the emission is free from the effect on the discoloration resistance of the colored fabric, and not only the discoloration resistance of the colored fabric reaches the relevant standard requirements, but also the said for various fibers. The adaptability of the coloring technique will also be good.

The drying by radiation may be specifically drying by infrared radiation. For example, an infrared radiating lamp or an infrared radiating lamp group can be used to illuminate the substrate or to be dried with microwaves. In the specific implementation process of the present disclosure, a microwave drying method is used , microwaves having a frequency of 2.45 GHz ± 25 MHz are selected, and the drying temperature is set to 200 ° C. or lower. Microwave drying may be completed in an atmospheric environment (normal pressure environment) or a vacuum environment.

The temperature of the above microwave drying should be slightly lower than the temperature resistance T of the woven fabric. For example, it can be understood that the temperature resistance of the woven fabric (T-10) ° C. or lower is set to avoid the embrittlement phenomenon of the fibers. The corresponding drying temperature can be reasonably set by the base fabric.

In addition, compared to the traditional drying method that uses hot air drying or electric drying, the microwave drying method has the advantages of short time, low energy consumption, no contamination, uniform drying, etc. Can't do damage.

Further, before the vacuum deposition described above, the base cloth after drying by radiation can be subjected to vacuum heat treatment, and generally, the heating temperature is 60 to 120 ° C. and the pressure is 3.0 ×. It is controlled to less than 10 ^{-3 Pa.} By carrying out the above vacuum heat treatment, moisture and gas, especially surface moisture and gas, are further removed , the woven fabric is prevented from reciprocating, and the adhesive force between the base fabric and the adhesive layer and the coloring layer is improved. can do.

In general, in the process of drying and heating the base fabric, the moving speed of the base fabric is controlled to be the same as the transmission speed in the subsequent vacuum deposition to realize continuous and smooth production of the entire coloring process. be able to.

Specifically, the above-mentioned textile coloring process may be completed on a vacuum deposition production line.
